If I omit -strict experimental, I get the usual error message:

encoder 'aac' is experimental and might produce bad results.
Add '-strict experimental' if you want to use it.
Or use the non experimental encoder 'libfaac'.

So the parser knows I've specified aac rather than libfaac, but it's
ignored, or at least, appears to be.

Well it actually uses aac, but displays libfaac, it's a bug I'll fix it
